Efficient Mixing in Drinking Water Reservoirs
Drinking water reservoirs play a central role in the management of safe access to drinking water in our cities and communities. The treatment and filtration processes necessary to produce drinking water can be costly. To ensure that the final product to consumers is of the highest standard, quality must be maintained within the storage facilities. Within the storage facilities, the water can deteriorate through “stratification“ leading to undesirable odour and taste variations, as well as critical chemical concentration variations which can result in the water
being outside regulatory guidelines.
Stratification in drinking water reservoirs impacts water quality. During the stratification process, different water layers develop different temperatures. There is no fluid exchange between these layers. This leads to algal formation, subsequent germination and/or uncontrolled chemical concentrations.
All this can easily be prevented by the implementation of a mixing element developed especially for water movement. This mixing system helps to displace the water layers and to prevent the layers re-forming.
The construction and the design of the HYPERMIX®-Agitator for drinking water reservoirs are based on INVENT’s successful hyperboloid mixing technology eEvo7 that they have adapted for use in drinking water reservoirs. For this reason, all the essential parts, as well as the mixer-body, are made from stainless steel SS 316 as well as the drive that is situated below the water surface and is designed to meet hygienic design directives DIN EN 1672-2:2009-07.
The INVENT HYPERMIX®-Agitator is supplied with an external control system that is used for start-stop and speed setting. The speed setting can be used for optimising chemical dosing, allowing the HYPERMIX®- Agitator to provide maximum fluid volume flow during the dosing process. This, in combination with the optionally integrated dosing point within the high turbulent zone, ensures complete micro-mixing prior to distribution to the entire tank’s contents.
